Presenter

Dr. Shuo "Sean" Pang, Assistant Professor of Optics and Photonics, CREOL, University of Central Florida

Conventional X-ray computed tomography (CT) only reconstructs the attenuation map. X-ray diffraction tomography (XDT) probes the angular-dependent scattering profiles of the three-dimensional (3D) object, achieving a high structural specificity among materials with similar electron density. However, due to the low level of interaction of coherent scattering, the practical imaging application using x-ray diffraction signature posed challenges in acquisition speed, algorithm efficiency, and reconstruction accuracy. In this talk, we will discuss the efforts in accelerating the image acquisition speed while maintaining object-specific information from the Optical Imaging System Lab at the University of Central Florida. Specifically, the talk will be focus on maximize the system detection efficiency and improve the classification/reconstruction performance for low photon detection level to meet the need of practical detection Dr. Shuo Pang is an Assistant Professor at College of Optics and Photonics (CREOL), University of Central Florida. He received his Ph.D. in Electrical Engineering from Caltech and conducted his postdoctoral research at Duke University. His current research focuses on developing computational imaging systems and processing methods for in both x-ray and visible regimes. He is a recipient of Ralph E. Powe Junior Faculty Award (2016) and SPIE Defense and Commercial Sensing (DCS) Rising Researcher Award (2017). He is the Chair of Optical Microscopy Group of OSA.
